Custom made round rubber pressure washer

A custom round rubber pressure washer should be matched to the contact surfaces of the assembly it serves. The inside opening, outside diameter and thickness establish where the rubber is located and how the mating faces compress it.

ETOL can customize dimensions, compound, hardness and color. Define the operating medium and loading conditions before choosing the material. The washer's contact area needs support from the surrounding hardware rather than overhanging an edge where rubber could be displaced.

Position the washer flat and centered before bringing the parts together. Inspect for an edge folding into the bore or material being pushed outward unevenly as the assembly reaches its specified condition. Evaluate any pressure-related sealing function on the complete arrangement. During maintenance, release the system according to its procedure before opening the joint, then inspect both washer faces and the seat. Replace damaged rubber and correct any local ridge or misalignment in the mating surfaces instead of adding force to close a joint that is not seated properly.

Material options

Rubber. Custom formulation and color for the intended contact conditions.

Hardness selection

Rubber: 30–90 Shore A. The inside opening, outside diameter and thickness establish where the rubber is located and how the mating faces compress it.

Custom dimensions

Set the round washer bore and outer boundary to the actual seat; define thickness against the space remaining at the intended closure.

Fit & assembly

Inspect for an edge folding into the bore or material being pushed outward unevenly as the assembly reaches its specified condition.

Use & inspection

During maintenance, release the system according to its procedure before opening the joint, then inspect both washer faces and the seat.
